Hannah goes back to her hometown (Gatlin) to find out who her mother is, but on the way she picks up a strange man who fore-shadows her life with a passage from the bible. When she gets there she wakes up Isaac from a coma he has been in for 19 years. Isaac is awake and wants to fulfill the final prophecy.

Hale, an American astronaut dies and is reincarnated with other persons who have lived throughout all of human history and end up on a mysterious planet called 'Riverworld'. The humans are left to their own devices and create tribal fiefdoms and succumb to brutal wars and raids. A mysterious race of hooded 'beings' oversee them - sometimes intervening, but their motives are unknown. Anyone who has ever lived and died on Earth comes here rather than 'the afterlife', even an extra-terrestrial call Monat, who had the unfortunate luck of dying on Planet earth in 2039. Hale leads a revolt and joins with others on a large boat to explore this mysterious new world.
